for a first its great!! definitely better than my beginning antics
in the future i would keep in mind anchoring down the camera so that it doesnt move as much. it also seems to zoom out and random places too. did you by any chance take each frame by hand? id advise either anchoring it more or getting an animation program or (my camera allows this) a third party app so that you can just take pictures from your phone and you wont even have to touch the camera!!
also, id try to stay away from natural light or florescent lights when animating. even though you cant see it with the naked eye, cameras can pick up the subtle light changes and its really distracting.
(this ones just more of a personal suggestion) itd be cool to see more movement in the subtle events, like characters falling over instead of just snapping down.
most importantly tho, if you're going to do stop motion animation, i would seriously suggest getting an actual program for animation, like
monkyjam, cus its free. they allow you to control your camera from your desktop so that you dont even have to touch it and it will make your animations infinity times better because cameras move SO much when you touch them. its always alarming how loving much they move just by pushing the button down with tweezers
